Washington’s state bird,the goldfinch’s main likely habitats are weedy fields and floodplains, where plants such as thistles and asters are common. They are also found in cultivated areas, roadsides, orchards, and backyards. American Goldfinches can be found at feeders any time of year, but most plentifully during winter.American Goldfinches are the only finch that molts its body feathers two times a year, once in late winter and again in late summer. The shining yellow color of the male goldfinches each spring is one welcome mark of approaching warm months. American Goldfinches breed later than most of the North American birds.
They wait to nest until June or July when milkweed, thistle, and other plantshave produced their gristly seeds, which goldfinches incorporate into their nests and also feed their young.Goldfinches are among the strictest vegetarians in the bird world, selecting a completely vegetable diet and only inadvertently swallowing an occasional insect.When Brown-headed Cowbirds lay eggs in an American Goldfinch nest, the cowbird egg may hatch but the nestling hardly ever survives longer than three days. The cowbird chick simply can’t survive on the all-seed diet that goldfinches feed their young.
American Goldfinches are energetic, acrobatic finches that balance on the seedheads of thistles, dandelions, and other plants to pluck seeds. They have a bouncy flight during which they frequently make their po-ta-to-chip calls. Although males sing raucously during spring, pairs do not nest until mid-summer, when thistles and other weeds have gone to seed. Goldfinches do not join other songbirds mobbing predators.Goldfinches move about south in winter following a pattern that seems to coincide with regions where the minimum January temperature is no colder than zero degrees Fahrenheit on average.Paired-up goldfinches make virtually identical flight calls; goldfinches may be able to distinguish members of various pairs by these calls.
The oldest known American Goldfinch was 10 years 9 months old when it was recaptured and rereleased during a banding operation in Maryland.American Goldfinches are monogamous and breed later in the summer than most other North American birds. They will wait to nest and breed until between late May and August. During the non-breeding season goldfinches will flock together, and their flocks can fly in a rising and falling pattern, which can look like a giant undulating wave of birds in the sky.
